We've been over this before; Scythes are a poor choice for a weapon, and those who think otherwise have poor opinions.

Everyone pointing out that a scythe is a terrible weapon in the real world are right. And yes, someone can go ahead and pull up war scythes for a pragmatic adaptation for poor folk who needed a weapon.
However,the OP has already stated it's an "impractical" weapon chosen "for aesthetic purposes." Choosing a scythe as a weapon in a game is appropriate if the game values style over historical accuracy and likewise silly if you want realism. The OP ceded this point at the start and asked about STYLE, not practical combat.
So yes in fantasy, no in Total War. The death symbolism, of death as the great harvester before whom all are cut down as so much wheat in the fall, pretty much guarantees it'll show up from time to time. Also, just the choice to use a scythe immediately tells you something about the character in universe. Instant characterization for the visually oriented or just plain lazy.
Back OT: Shadows of the Damned, Castlevania, NWNs and surely some of the other D&D based games, Chrono Trigger, some of the Ninja Gaidens, VtM Bloodlines (in the form of a giant pruning hook), Darkstalkers, the Drowning Doom horsemen in Brutal Legend...I can't think of many off hand. In a stylized, actiony game, it can be pulled off with sheer chutzpah. The Drowning Doom horse looked great in that 'verse.
